Question

Match List-I with List-II

List-I Parameter I	List-II Parameter II
(A) Solar energy	(I) Biomass
(B) Gasification	(II) Chemical energy
(C) Fuel cell	(III) Biogas
(D) Fixed dome	(IV) Water pumping

Choose the correct answer from the options given below

• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)
• (A) - (II), (B) - (III), (C) - (IV), (D) - (I)
• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)
• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)

Hint:

In matching questions, identify the most certain pair first.
For example, matching fixed-dome with biogas immediately narrows down the choices, helping you find the correct option faster.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This problem requires matching key renewable energy resources and conversion technologies with their corresponding technical applications or energy systems.

Step 2: Detailed Explanation:
Let us analyze each pair.
1.(A) Solar energy: One of the most common applications of solar energy in agriculture is solar water pumping, which uses solar photovoltaic arrays to power irrigation pumps.
Thus, (A) matches with (IV).
2.(B) Gasification: This is a thermochemical process that converts solid carbonaceous materials—primarily biomass—into a combustible gaseous fuel (producer gas).
Thus, (B) matches with (I).
3.(C) Fuel cell: A fuel cell is an electrochemical device that directly converts chemical energy from a fuel (like hydrogen) into electrical energy.
Thus, (C) matches with (II).
4.(D) Fixed dome: The fixed dome design (such as the Chinese fixed dome digester) is a common, reliable structural design used for biological anaerobic digestion to produce biogas.
Thus, (D) matches with (III).
Combining these matches:
\[ \text{(A)-(IV), (B)-(I), (C)-(II), (D)-(III)} \] This combination corresponds to Option (D).

Step 3: Final Answer:
The correct matching sequence is (A) - (IV), (B) - (I), (C) - (II), (D) - (III).
